Building either libmpcdec 1.2.3 or 1.2.4 with mplayer results in complete noise/garbage output when decoding .mpc files. Building with MinGW for windows that is, if that may possibly be the issue. I have no idea how to test the lib itself in Windows, so I suppose it could just be mplayer?

An acquaintance of mine who also builds mplayer actually pointed it out at first in his builds with 1.2.4. I simply confirmed the same and checked 1.2.3 as well to find the same garbled output. 1.2.2 is the only version I have ever used before and it still seems to work in latest svn builds of mplayer. Also if it matters at all the files I was trying to play are of the older variety, afaik. I don't use Musepack much but I had some older encoded files around using mppenc 1.15v.

I don't really know if the problem is old support for the musepack decoder in mplayer or if it is just a windows related build issue. Since things are picking up around here I decided to report what I've found at least. Perhaps you can find the problem.

Yes, i've noticed that as well and didn't have time to check out why (same issue on win32 & posix).
The good news is that ffmpeg now have their own native musepack decoder (http://lists.mplayerhq.hu/pipermail/...er/050235.html)
Mplayer will eventually be able to play those files through it soon.

Bump. I thought I recalled reading on one of the mplayer mailing lists that the issue I described above was fixed in libmpcdec. However I notice an "official" src release has not taken place since 1.2.4.

Have I been hallucinating about bug fixes that aren't really there , or is there a fix in SVN?
